This is a script to determine what installation cluster(s) are required to get a given package to be installed on Sun Solaris. Sample with Solaris Grep: # ./getcluster.sh SUNWapchr SUNWapchr is in cluster SUNWCapache => Installation Cluster(s): SUNWCXall SUNWCall SUNWCprog # This tells us that the SUNWCprog, SUNWCall and SUNWCXall installation clusters will provide the SUNWapchr package. Sample with GNU Grep (which is /usr/sfw/bin/ggrep these days) - the same, but more information about the clusters and metaclusters: $ ./getcluster.sh SUNWapchr SUNWapchr is in cluster SUNWCapache Apache Web Server The Apache Web Server Sun Microsystems, Inc. 1.3.9 => Installation Cluster(s): SUNWCXall Entire Distribution plus OEM support A pre-defined software configuration consisting of all software included in the operating system release, plus OEM platform support. SUNWCall Entire Distribution A pre-defined software configuration consisting of all software included in the operating system release. SUNWCprog Developer System Support A pre-defined software configuration consisting of the typical software used by software developers. $
